I have a Joomla 3 site using the shaper-newedge template, but for some reason it started displaying a blank page. I want to migrate it to a more recent version of Joomla and load the new template that's in Joomla 5. I'm migrating my articles using J2XML, but it's not migrating the article images or the featured image from Helix 3 Blog Option. How can I migrate all my articles?
